The Serial ATA cable is smaller and more flexible allowing easier
routing inside the chassis. The lower pin count of the Serial ATA
cable eliminates the problem caused by the wide, flat ribbon cables
of the Parallel ATA interface.
Hot plug support for Serial ATA drive and connections are not
available in this motherboard.
®
Install Windows XP™ Service Pack 1 when using Serial ATA.
